This one, right?
-i[SUFFIX], --in-place[=SUFFIX]
edit files in place (makes backup if extension supplied)
-i copies the content to a temporary backup file, truncates the
original (keeping permissions, ACL flags etc) and starts processing
from backup to original file, right?
Which purpose has this option (I can't look at the GPL code without
getting tainted by the GPL):
--follow-symlinks
follow symlinks when processing in place
If you use one sed script over many files then sedcomp will help you
(precompiles sed script, saving execution time in the processing
loop).
